Can anyone help with instructions/downloads to take my LG G Pad X 8.0 down from nougat to marshmallow? I have not rooted yet, but have the bootloader unlocked. I have downloaded the KDZ, but my attempts to flash it have been a miserable failure...
Thanks for all you do!

You can use LGUP with one of the Marshmallow kdz's to downgrade. Essentially if you follow steps 1 and 2 at https://forum.xda-developers.com/g-pad-x-80/how-to/nougat-7-0-v521-guide-to-update-v521-lg-t3533338 and use the v52110c or v52110e kdz instead you'll be back on Marshmallow.
tried and failed
I got the LGUP to work with uppercut and it seemed like things were going to work this time, but it gets stuck at 10% each time and gives message, "Error: 0x2bc, invalid command response code = 0x80000121. Could it be hardware problems with my tablet? I have some strange things happening recently, but attributed it to trying to run dirtycow with a patched version of android a few months back. One thought, does it matter what port the device uses on windows 7?

I recently received both my Nexus 5 and LG G4 second hand boot-lopped and I, with prior experience, hopped to restore them. I downloaded all the images and firmware needed and tried to get the most recent versions to avoid any downgrade problems. Then everything went south. Using the lg tool, the G4 got flashed 100% but then that was it. It would not boot up and not turn on. My computer would recognize it but it would leave me a "Unknown USB Device (Device Descriptor Request Failed)" message. At that point I lost hope and moved onto the nexus 5. I used wugfresh nexus root toolkit and went through the usual process of unlocking boot loader and downloading image. Well when it started to flash boot.img it restarted and that was it as well. Now both my nexus 5 and lg 4 are dead and leave me the same message when plugged in. I'm very confused as to what has happened. I've done this dozens of times before and it has never given me this. I believe they are hard bricked now and i dont know why. Is it Windows 10 anniversary update? Is there a solution? I'm desperate and lost at this point because I cant find anything online. (Not able to access recover mode on either). Please help.
Check this out, there are a couple of videos too. Also, how did you flash your nexus 5 image, did you use adb or fastboot? As for the LG phone, take a look at this thread, it might be a hardware issue that is LG's fault.

Thanks I'll look into it. As for the Nexus 5, it was done through adb. The thing I'm not understanding is why it happened. Usually my nexus devices don't get bricked like this and it weird that it happened to both of them

I recommend flashing via fastboot instead (fastboot flash boot.IMG) But you'll have to look into the link to solve the driver issue.
Hi everyone!
I recently bought a LG V10 h961n from eBay. I had no interest in root, so I updated it to marshmallow. However, I encountered huge wi-fi connectivity problems: the phone would connect to WiFi, but only really close to the router, and the latency was unexplainable high. The only workaround I have have found was a guide posted here in XDA which required root.
So, I started digging and I found a tot file of lollipop already rooted. I downloaded the kdz for lollipop hoping to downgrade using lgup and/or flash tool. All the flashing end with a 0x2000 error code in lgup and a "contact your system administrator" error on flash tool.
Now,the phone is stuck into download mode whatever button I press: power to boot normally, power+volume down or up.
The only combination working differently is volume up+down+power that bring me to the IMEI.
In the end, i was hoping that someone was able to find a solution. I really love this phone, and I would really feel bad if I had to throw it away and buy another one.
Thank you in advance.

It is, but it keeps rebooting over and over until I unplug it...
Solved, just kept trying to connect to lg bridge. In the end it detected my phone and installed the os by clicking on "update error recovery". Hope you'll solve too!
I was running a MarshMallow update for the last 6 months and suddenly today morning I just decided to flash the "rootedsystemh960a.tot" from one of the forums here at XDA. First it did flashed the ROM using LGUP but then the Phone was stuck with LG LOGO for minutes and then I flashed it again with my stock UAE MM 6.0 ROM. It did work. Then I reflashed again hoping for the ROOTED ROM to work on my phone and ever since LGUP is giving me this error code with a message " lgup error code 0x2000 invalid command response" and it keeps crashing. Now I have tried to switch windows and tried to flash many ROMs and it wont stand a chance. Why this error message is coming? Can anyone of you experts figure this out? Even the COM ports are matching at LGUP and in my DEVICE MANAGER. Please help me. I am stuck with this mobile. ...:crying:
Little info about my phone. It is a UAE/DUBAI Variant of LG V10 - H960A, and officially I am not allowed to unlock my BOOTLOADER by the LGE itself. I had tried before bootloader unlock modes.. Anyways its not the point here right now.. The main thing is LGUP is crashing again and again.. Is there any other utility in place of LGUP for flashing LG ROMS ????
Well that .tot file was for Lollipop only that was your mistake in this probably and it has corrupted your system somehow. I'm afraid I have no idea how to deal with this phone as I don't modify this one myself because of the lack of development/devs.
I think there is something called LGFlashTool also.

Even flashtool aint doing a job.. When I try to run Get device info from within the LG FlashTool, the application crashes...God! Cant they develop some stable running apps for their customers?
Hi,
can you enter the download mode on your V10? Then it might be possible to flash a clean (unrooted) MM via LG Bridge. Some time ago I tried to install the latest MM Version V20e on my V10 with LGUP. For some reason that failed and left me with a phone without ROM, too. Afterwards the V10 was not recognized by LGUP anymore.
Luckily I was still able to enter the download mode manually. So I connected the phone to my PC and started LG Bridge which still did recognize it as a V10 H960a. So selecting Firmware update and then clicking in the bottom right corner of the window on a link saying something like "repair flash errors" or "repair update errors" (I'm currently at work and cannot check) did a complete clean install of the latest firmware.
Maybe you're lucky and this works for you too.

Well hello, I found the solution for my problem and I was able to flash the ROM successfully. Its some kind of new utility amalagamated with LGUP and it does flash without any problems. Found out it was related to some corrupt dll file or incompatible file I had in my LGUP library for the ROM FLASHING to fail all the time... You just read this first post on this link and you will be all fine. Trust me ...:highfive::good::fingers-crossed::fingers-crossed:
https://forum.xda-developers.com/lg-g5/development/uppercut-lgup-loader-g5-variants-t3511295
Just dont forget to follow the rules exactly as mentioned and if you can run it in the Virtual Machine I would prefer you to do that but you have to do everything like installing LG DRIVERS + LGUP + LGUP DLL FILE + UPPERCUT as mentioned in this post. Because if you are running antivirus on your PC, it will detect this UPPERCUT TOOL as some trojan horse or some kind of malware. I did that in my VM as I already had my VM configured for my LG V10 Flashing process.
Do it and do let me know should you encounter any problem. May be I can help later on.

Hello.
So when I tryed to update my LG G6 to 9.0 everything went allright but it got stuck on boot screen. I can still go into download mode and fastboot but the device is not rooted nor is bootloader unlocked. Only thing I have is USB debugging.
I tryed reflashing it again through LG UP but it gets stuck at 4% drops this error: Error: 0x81000302, Please use latest DLL LAF Protocol version is not match DLL = 0 Device =117985312.
Then I also tryed to go into download mode and use LG Bridge update recovery fix. But that also didn't work. It dropped this error: update fail error code 0x5a32suffx lg h870.appbk.
And I also tryed using LG Flash Tool 2014 but that also didn't work. It dropped this error: Required info cannot be found. Contact the system administrator...
So please, could anyone help me fix this problem?
